Not a baby bunny but I was once charged by a blind rabbit. I was shooting some old .22 longs in my rifle as I had run out of my normal ammo and found an old packet. The rifle was not sighted in for this ammo but I thought it might hit close enough. I could have said "it gave a mean look like I owed it money" but as it was blind with myxomotosis that wasn't likely.

I missed the incredibly frightening charging rabbit, also known as the grey death, charge with the first 4 shots and held off the last cartridge for an end of barrel killing shot and so saved myself to hunt the grey death another day .... I thought about making a film 'Death at my feet' but the title was already taken. Plus I washed my feet anyway ...
